To aZZ whom it may concern: 7

Be it known that I, Josnri-r GoULDBoUnN, a subject of the King of Great'Britain, residing at Leicester, in the county of Leicester, England, have invented certain new and useful Improvements in Sole-Leveling Machines; and I do hereby declare the following to be a full, clear, and exact description of the-invention, such as will enable others Skilled in the art to which it appertains to make and use the same.

The invention relates to soleleveling machines, and more particularly to that class of machines in which the leveling operation is efi'ected by the rubbing action of a rotating leveling roll which is applied under pressure to the sole of a shoe, and is caused to travel along. the shoe sole by relative movement of the roll carrier and jack upon which the shoe is supported. In operating upon certain classesof work with machines'of this type it is desirable that the roll be moistened, and the object of the present invention is to provide means for automatically controlling the supply of m'oistening liquid to the leveling roll or rolls, so thatthe shutting off of the shutting 0d the supply of liquid to the roll, a

and this means may be operated by any suitablemoving part of the machine. It is preferred, however, to so construct the means for controlling the supply of liquid to the roll that it will operate to start and stop the supply of liquid at predetermined times in each levelingoperation, so that the predetermined quantity of liquid requisite for securing the most eflicient operation upon the shoe may be automatically delivered to the roll during each leveling operation.

The various features of the invention will be readily understood from an inspection of the drawings, and the following detailed description of the mechanism illustrated therein.

a In the drawings, Figure 1 is a sectional,

elevation showing so much of a sole leveling mach ne as 1s necessary to illustrate the appl cation of the preferred form of the present invention thereto; Fig. 2 is a sectional plan f view on anenlargedscale taken on theline 22 of'Fig. 1; Fig. 3 is a vertical section of the valve which controls the supply ofliquid to the distributing device; Fig. 4 is a section on line 44 of Fig. 3'; and Fig; 5 is a vertical section of theliquid distributing device.

The machine shown herein comprises two sole supportlng jacks 2, and two cobperating sole pressing rolls 4, one only of each of these parts being shown in the drawings. Each of the-rolls 4 is journaled at the end of a carrier arm 6, springs 8 acting upon the arm to maintain the roll in contact with the sole of a shoe supportedon the jack. The rolls are rotated in their carriers by mechanism which need not be described,since it forms no part of the present invention.

The machine is provided with a cam 10, and withmechanism by which each ack in turn can be coupled to this cam. so that the jack 1s oscillated beneath the leveling roll to cause the point of operation of the roll to travel along the shoe sole. This mechanism may be the same as that shown and described in Patent No. 555,548, March 3, 1896, and need not be herein specifically described.

According to the present invention, the frame ofthe machine" is provided with a bracket 12 which supportsa water tank 14 secured thereto byascrew 16, which tank has an outlet pipe provided with a tap 18 by means of which the flow of liquid from the tank maybe turned on or off or'regulated as required. 'Screwed upon, or otherwise secured to the end of thepipe from the tank is a member 20 in which isformed a conical recess which constitutes a seating for a conical valve 'spindle. 22 (see particularly Figs.

3 and 4). The member 20 is provided with three holes, one 24 leading from the said re- 3 3 cess to the outlet pipe of the tank, and two others 26 leading from the recess to nozzles 28 formed on the member 20. The nozzles are connected by flexible .tubes 30, to two liquid distributing devices 82, one for each leveling roll. The valve spindle 22 is bored longitudinally at 84, and is also provided with radial holes36 which ezitend into the longitudinal bore 34, and which, when the spindle is turned into the open position as shown by the dotted lines in Fig. 4, are

the spindle through a washer 42 that rests" on the top of the member 20.

The lower end of the spindle 22 is cupshaped, and receives the ball-shaped end of a vertical rod 44 which is carried in ears 46 i and 48 formed on the bracket 12, and is held from longitudinal movement by a pair of collars 50. and 52 attached to the rod on each side of the ear 48. The ends of a pin 54,

passing through the ball-shaped end of the rod 44, engage the walls of vertical slots, one of which is shown at 56 (Fig. 3), out in the cup-shaped portion of the spindle 22. Thismethod of connection insures that the spindle 22 and rod 44 shall turn as one without danger of breakage or jamming of the parts, should the axes of the rod and spindle be slightly out of alinement. From the collar projects an arm 54 carrying a roll 56 which is held by means of a spring 58 attached at one end to a hook 60 (see Fig. 2) on the collar 52, and at the other end to a hook 62 on the bracket 12 in position to be engaged by a wedge-shaped cam or dog 64 carried by the cam 10 which is employed to oscillate the jacks. The spring 58 tends to maintain the valve closed. The collar 52 is provided with a stop 66 which engages with a cooperating stop face formed upon the bracket 12 when the valve is closed by the action of the spring 60.

Each of the liquid distributing devices 32 comprises a member 68 from which extends a damping pad 70 of felt or light material that bears upon the corresponding leveling roll 4. The pad 70 passes through a slot in the member 68, its inner end being located in a chamber '72 formed in the member. The member 7 2 is mounted upon a casing I 74 which contains aportion of the mechanism for rotating the roll, or may be otherwise so arranged that it partakes of the movements of the roll carrier. Screwed into the member 68 is a part 76 which comprises a nozzle 78 which receives one of the flexible tubes 30 connected with the two nozzles of the valve member 20. Passing through the nozzle 78 is a hole 80 which leads into a recess 82 in the part 76, and from thence by way of an aperture 84 and a hole 86 into the chamber 72, so that the end of the pad within the chamber receives the liquid delivered from the supply tank by the opening of the valve 22. The top of the aperture 84 is conical in shape, and is adapted to receive the conical end of an adjusting screw 88 to regulate the rate of flow of liquid to the pad. The screw is screwed into the nozzle 7 8 and is provided with a lock nut 90 so that it may be locked in adjusted position.

' In the operation of the machine a shoe is placed upon'one of the acks 2, the jack is then coupled to its guiding mechanism, and

the machine started. The cam 10 then operates to oscillate the jack beneath the leveling roll 4, and during this rotation of the cam the dog 64 strikes against the roll 56, thereby operating the rod 44 and opening the valve to allow liquid to flow from the tank 14 to the delivering devices 32. When the dog 64 passes from engagement with the roll 56, the spring 58 acts to turn the rod 44 reversely, and closes the valve so that the supply of liquid from the tank is suspended. After the leveling operation upon the shoe has been completed, the machine is automatically brought to rest, and the other jack, upon which the operator has placed another shoe while the machine was operating upon the preceding shoe, is now coupled to its actuating mechanism and the machine again started.

It will be noted that by this construction, while the machine is at rest the supply of liquid from the tank is stopped, and further, that the amount of liquid which is delivered to the distributing devices is predetermined by the machine as the valve is opened by the action of the dog 64 and spring 58 for a predetermined time in each sole leveling operation( The quantity of liquid, however, is under the control also of the operator, since by opening the tap 18 more or less, he can regulate the amount of liquid delivered to both the delivering devices 32, or by means of the adjusting screw 88 he can control the amount of liquid delivered from each of said, devices.

'Although for the sake of simplicity only one automatically controlled valve is used to supply liquid to both of the leveling rolls, and thisvalve is controlled from the cam that is common to both jacks, it will be understood that separate valves may be employed for each jack, and that the valve or valves may be controlled by the movements of other parts of the machine. Moreover, although it is preferred to automatically control the opening and closing of the valve through which liquid is supplied to the distributing devices, it will be understood that this is not essential to the broader features of the invention, and the automatic stopping of the supply of liquid to the rolls when the machine is not in operation may be otherwise eti'ected without departing therefrom. It will also beunderstood that the specific construction and arrangement of the parts may be otherwise varied and modified as found desirable or best suited to the construction of machine in which the invention is embodied. V
